Description
Technical field
The present invention relates to a kind of pick-up unit, be specifically related to a kind of transformer pick-up unit.
Background technology
Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.Major function has: voltage transformation, current transformation etc.Transformer application is very extensive, and therefore the detection of transformer is the main points in transformer serviceable life, and existing structure of the detecting device is comparatively complicated.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of transformer pick-up unit.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of transformer pick-up unit, comprises power supply, current sensing means, voltage check device, load and rectifier; Described power supply is connected with the elementary of transformer, described current sensing means detects the electric current of primary, the input end of described rectifier is connected with the secondary of transformer, and the output terminal of described rectifier connects load, the voltage at described voltage check device sensing lead two ends.
Whether described transformer pick-up unit also comprises power light, connect normally in order to detect power supply.
Whether described transformer pick-up unit also comprises load pilot lamp, connect normally in order to the secondary of transformer.
The beneficial effect that the present invention reaches: the present invention when transformer is fully loaded with work by voltage check device, is measured output voltage and the calculated value voltage-contrast of secondary full load, chooses qualified transformer; Structure of the present invention is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Fig. 2 is the circuit diagram of an embodiment.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of transformer pick-up unit, comprises power supply, current sensing means, voltage check device, load, power light, load pilot lamp and rectifier.
Power supply is connected with the elementary of transformer, current sensing means detects the electric current of primary, the input end of rectifier is connected with the secondary of transformer, the output terminal of rectifier connects load, the voltage at voltage check device sensing lead two ends, whether power light connects normally in order to detect power supply, and whether load pilot lamp connects normally in order to the secondary of transformer.
Above-mentioned transformer pick-up unit, transformer full load (general work is more than or equal to 8 hours), voltage check device measures output voltage and the calculated value voltage-contrast of secondary full load, chooses qualified transformer, and structure is simple, easy to use.
As shown in Figure 2, transformer has three output terminals, and the elementary input voltage of transformer is power supply is GB voltage, and namely electric power output voltage is GB voltage; Current sensing means has two kinds of situations, specific as follows: a kind of is place a resistance in the primary circuit of transformer, and the dividing potential drop on measuring resistance, calculates electric current; The second removes resistance, directly measures the electric current in circuit at resistance place series current table; Power light, the bright primary input terminal representing transformer of lamp has power supply, and lamp goes out, and does not have power supply or primary to open a way or short circuit; The alternating voltage (AC) that transformer secondary output exports by rectifier converts DC voltage (DC) to, is more close to use; Operation at full load, load pilot lamp, lamp is bright to be represented load and normally works, and voltage check device measures output voltage and the calculated value voltage-contrast of each secondary full load, chooses qualified transformer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
